Two versions of the Samsung Galaxy S5 will be released when it hits the shelves next year with rumours that one will feature Samsung’s curved display technology.

ETNews, a South Korean newspaper, reports that the top-of-the-range smartphone will come in two forms with one sporting the polycarbonate body similar to the current model and the other including a metal body with flexible OLED screen.

As far as the device specifications go, SamMobile reports that both devices will have a 2K-resolution display, 16-megapixel camera, a huge 4,000mAh battery and run on Android 4.4 KitKat. The two devices will differ in the processor department with one having an Exynos 64-bit chip and the other powered by a Snapdragon processor.

Samsung could also release a new version of the Galaxy Gear smartwatch alongside the Galaxy S5 like it did with the Galaxy Note 3 earlier this year. The second version of the wearable device is rumoured to be between 15 and 20 per cent thinner than the original with other improvements yet to be leaked.

If the next version of Samsung’s flagship Galaxy smartphone comes with a curved OLED display it will be the second Samsung device to have one and the firm will be hoping it shifts more units than the Galaxy Round that has sold an average of just 100 units per day so far.

Samsung’s Galaxy Gear smartwatch range could also get a boost if launched alongside the Galaxy S5 smartphone with the current version also suffering in the sales department with just 800-900 units being sold per day.

Some rumours say the device is expected to go into mass production in January 2014 before it is released in March 2014, whilst others have Samsung teasing a prototype S5 at CES 2014 before potentially launching it at MWC in February.
